A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

A device, kit and method for the correction of spinal deformity using an anterior approach. The device comprises a screw-head platform, wherein the screw-head platform comprises a primary recess for receiving a primary rod, and a main vertebral body screw rotatably connected to the screw-head platform .

A modular system for a surgical device is provided. The modular system includes an adjustable-length portion having a first end and a second end, the first end spaced apart from the second end along a length of the adjustable-length portion, and the adjustable-length portion including an actuator configured to be activated to change the length of the adjustable-length portion. The adjustable-length portion is configured to be secured to one or more bones. The modular system further includes a first fixed-length portion configured to attach to the first end of the adjustable-length portion to form a first surgical device.

A surgical instrument comprises a first portion defining a cavity configured for disposal of a first implant support member. A second portion defines at least one passageway aligned with the cavity and including a guide engageable with a second implant support member to orient the second implant support member with the at least one passageway such that the second implant support member is connectable with the first implant support member. Systems, spinal constructs, spinal implants and methods are disclosed.

A reduction jack for placing a spinal rod within a rod channel of a bone fixation screw includes a mounting stem having a tubular body, a plurality of teeth disposed on the body, a pair of legs projecting from the body, and catches disposed on the legs for engaging the bone fixation screw. A reduction sleeve at least partially encircles the mounting stem. A gear assembly is mounted on the reduction sleeve and engages the teeth on the body such that manipulation of the gear assembly facilitates movement of the reduction sleeve along the mounting stem. A first pawl is pivotably mounted to the reduction sleeve and resiliently biased against the teeth on the body, the first pawl being pivotable between a first position where the first pawl engages the teeth on the body and a second position wherein the first pawl does not engage the teeth on the body.

The invention relates to a medical instrumentation with a navigation system which comprises an optical detection unit comprising a camera, and a data processing unit coupled to the detection unit, with a stabilization element of a surgical fixation system and with a medical marking device which is held in a defined spatial arrangement on or is comprised by or formed by the stabilization element, the location and orientation of the marking device in space being determinable with the navigation system, it being possible for at least two images of the stabilization element and the marking device to be taken from a different orientation by means of the detection unit and for the shape of the stabilization element to be determined by the data processing unit on the basis of the two or more images. The invention also relates to a method for determining the shape of a surgical stabilization element.

A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.

A stabilizer device for the spinal column, comprising a first body (2) and a second body (2) adapted to be mutually connected by a rod-like element (5), the first and second bodies (2) being adapted to be fitted around first and second pedicle screws (3), which are adapted to be inserted in turn in two mutually adjacent vertebrae, the first and second bodies (2) being fixable on the pedicle screws (3), the first and second bodies (2) being fork-shaped and adapted to accommodate locking means (20), the locking means (20) being adapted to pass from a position for accommodating the pedicle screw (3) to a position for locking the pedicle screw (3) within the fork-shaped body (2).

Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and derotating the spine to correct the spinal deformity by adjusting an effective length of the lateral coupling, and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

A spinal stabilization system includes a connecting rod, a rod bending device, and a plurality of bone screws. The connecting rod includes an elongate round portion, an elongate head portion and a neck portion connecting the elongate round portion with the elongate head portion. The rod bending device includes an elongate body defining an aperture configured and dimensioned to receive the connecting rod therethrough in a single orientation. The bone screws include a housing portion and a screw shaft distally extending from the housing portion. The housing portion includes an inner housing and an outer housing slidably surrounding at least a portion of the inner housing. The inner housing defines a slot configured and dimensioned to releasably secure the elongate round portion of the connecting rod therein. The outer housing is movable relative to the inner housing between an unlocked state and a locked state.
